1SP0335 SCALE™-2 Plug-and-Play IGBT Driver 1SP0335 Series Single Channel Driver 6.5 kv/4.5 kv with Separate Power Supply Unit for high voltage IGBT Modules (10.2 kv Iso). DC/DC converter ISO5125I connected to 1SP0335D (slave) with 1SP0335v (master) each screwed onto a 6.5 kv IGBT module. PrODUCT DESCrIPTIOn KEy BEnEFIT The 1SP0335 SCALE™-2 Plug-and-Play drivers are specifically designed for the reliable and safe driving of 130x140 mm and 190x140 mm IGBT modules with 10.2 kv isolation voltage and blocking voltages from 3.3 kv to 6.5 kv. They are optimally suited to high-reliability applications in railway technology and industry. The driver concept relies on a master-slave principle that allows the safe operation of parallel connected IGBT modules. The master (1SP0335v or 1SP0335S) can be used as a stand-alone driver without a slave to drive a single IGBT module or with up to three 1SP0335D slaves, to drive up to four parallel connected IGBT modules. The master is equipped with a fibre-optic interface and global fault management. In master-slave configurations, the slaves are connected to the master by a bus cable which distributes the common command signal and the secondary-side supply voltages for the DC/DC converter. The 1SP0335 drivers are based on Power Integrations highly integrated SCALE™-2 chipset. Thanks to SCALE™-2 technology, the new 1SP0335 family comprises highly integrated, high-performance, complete and extremely compact single-channel IGBT drivers. Page 36 The SCALE™-2 chipset reduces the component count by 85 % compared to conventional solutions, thus significantly increasing reliability and reducing costs. The drivers are equipped with Dynamic Advanced Active Clamping (DAAC), shortcircuit protection, regulated turn-on gate driving voltage and supply-voltage monitoring. Perfectly matched driver versions are available for all mechanically compatible IGBT modules. The plug-and-play capability of the driver allows immediate operation after mounting. The user needs to invest no effort in designing or adjusting it to a specific application.

Thanks to this modular concept, any driver unit that was developed to match a specific IGBT module can be used for any required insulation specifications. Only the separate power supply unit ISO5125I must be chosen to a specific application. Page 37
